What is Climate Change?
Climate change is a long term alternation of temperature and specific change in weather patterns. Human population are increasing and effect on climate change in atmosphere. Burning fossil fuels, farming livestock, cutting down forests are the causes of the increasing temperature of the atmosphere. These all causes result in the formation of greenhouse gases in the atmosphere and increase the risk of global warming.
Climate change is vulnerable to human health. Factors are affecting on climate change and creating more heat stress, poor quality of air, many waterborne diseases and diseases caused by rodents or insects. Some negative effect on living and non-living things like droughts, storms, melting glaciers, rising sea levels directly affect and harm individuals.
Explain the Term Greenhouse Effect and How it Affects the Earth Climate
The greenhouse effect is the natural process in which the earth atmosphere warms, and the sun’s energy comes to the atmosphere surface; some of the energy is reflected and some of it is radiated and absorbed. The absorbed energy involves in warming the atmospheric surface.
Greenhouse gases in the atmosphere absorb radiations of heat. The human population is increasing day by day and adding greenhouse gases in the atmosphere; for example, due to the industrial revolution, more heat is produced that increases the atmospheric temperature.
What is Global Warming and What Contributes to it?
Global warming is the rapid increase of the earth atmosphere due to greenhouse gases. Human activities are too much involved in causing global warming. Due to human activities, greenhouse gases add to the atmosphere and increase the temperature.
Greenhouse gases produce due to the burning of fossil fuels. It results in to increase in the temperature of the earth surface. The burning of oil, gasoline, and different chemicals produce heat-trapping gases in the atmosphere and cause global warming.
What Are the Factors That Lead to Global Warming and Elaborate Steps to Prevent it
Some Factors Lead To Global Warming
- Natural gas drilling
- Oil fertilizers
Some Preventions to Prevent Global Warming
- Many heat-trapping gases like nitrogen, carbon dioxide, chlorofluorocarbons cause global warming in the atmosphere, so you should prevent the atmosphere from these gases.
- The burning of oil, gasoline and coal is also the big cause of global warming. So you prevent yourself from burning that type of things and fossil fuels.
Factors Affecting Climate Change
There are several factors that affect on climate changes.
Latitude is the major factor of climate change. Latitude means how far and how close it to the equator, this is too important, and it depends on sunlight concentration. Latitude has a big control on climate.
Latitude affects the temperature by influencing the seasonal range because different latitude receives different solar radiations. Latitude is related to the height above sea level as we know that temperature decreases with increasing temperature. The rise in altitude causes a decrease in temperature to create a cooling effect known as condensation.
Ocean currents have different temperatures. Cool ocean currents cool the air which become a cause of cooling the coast, while warm ocean currents warm the air that result the warming of coast. This helps the coast to maintain temperature.
Ocean currents are also one of the essential factors affecting on climate change. Ocean currents regulate the global climate, which is very helpful in the uneven distribution of solar radiations. Ocean currents cool or warm the water and increase or decrease the temperature of earth atmosphere. Warm or cool ocean currents affect the coastal region of the atmosphere.
Wind Or Air Messes
Wind and air messes are the big factors of climate change. Warm grounds increase the temperature that results in the air pressure low. When it rises, it becomes cool and comes back to the ground due to low pressure. This cycle repeats and create wind.
The air messes are too helpful in changing climate. It helps to absorb all the air in the climate. Air masses control the weather; weather patterns while hot, cold or moist depend on air masses. For example, Maritime air masses originate from the ocean, and here, the weather is moist.
Elevation means when you go higher, the cooling is increasing. The air in higher portion will expand due to the low pressure that results cooling effect. When air rises, the molecules spread down, and the temperature and air pressure increases.
For example, at high, if the humidity is at 100 percent because of snowing, then the temperature decreases. Elevation increases make the weather colder, while elevation decreases make the weather warmer, so elevation and climate are directly related.
Relief is the rising of land, when air rises over some part of land, then the temperature decreases that results in the condensation process increases. That’s why water droplets fall down due to heaviness.
But when the air goes higher, both the temperature and pressure increases, while condensation decreases. More rainfall occurs in the mountains than in other areas, but in high-level areas, moist air cool down and cause heavy rainfall.
Temperature and climate are closely related to each other. Higher temperature produces heat waves and becomes a source of hot weather, while cool temperature causes cold and dry weather due to decreasing the earth’s temperature.
Warmer temperature affects the oceans and weather patterns, snow, ice, and other living things. The melting of glaciers is also the major cause of warm temperatures. Temperature affects air movements because temperature is a physical quantity while climate is quantitative.
Large water bodies, for example, in oceans, lacks and rivers affect the climate. The water heats and cool down easily; that’s why coastal regions are warmer in winter and cooler in summer.
When water molecules become warmer, then these molecules interact with air, so this process is known as evaporation. Large water bodies help to absorb and release heat in coastal regions. A large water body has more heat capacity than land, and it is involved in cooling the temperature of the water.
Atmospheric pressure is the best indicator of weather. When air pressure is low, then it results in cloudiness, precipitation, and wind. While in the case of high pressure, the weather is a fairy, normal and calm.
Rising air causes low pressure, while the sinking of air causes high pressure. Due to low pressure, oxygen availability in the atmosphere decreases. Air pressure-totally change the climate because air pressure controls the moisture movement and atmosphere circulation.
Volcanic eruption is also the basic factor of climate change. Volcanic eruption changes the weather in two ways. Firstly, greenhouse gases add to the atmosphere due to volcanic eruption and the temperature increases that results in global warming in the atmosphere.
Secondly, volcanic eruption causes leakage of sulphur dioxide when this gas combines with water and causes sulphuric acid droplets. These sulphur dioxide droplets block the sunlight on the atmospheric surface and cause cooling of temperature.
Solar radiations and weather patterns are related to each other. Solar radiations are those radiations that are not reflected or absorbed. These radiations are absorbed by greenhouse gases and then radiate energy from all directions.
Atmospheric radiation affects climate; when heat enters into the atmospheric surface by sunlight, it causes the formation of clouds. Solar radiations control the energy level of the atmospheric surface.
Moisture is also one of the most significant factors are affecting on climate change. When warm air holds the moisture, then warm air increases the temperature of the air. This circulation of air and moisture cause the formation of dark clouds.
At higher humidity, the air contains more moisture. While the air temperature is low, then the moisture content in the air is also low. Moisture contents in summer are higher as compared to winter. Warmer temperature causes more humidity than cold weather.
Sun is the best source of light. So the sun is also a big source of changing climate. The heat that comes from the sun warm the weather results in increasing temperature, stir air and ocean currents, catalyzing different reactions in the atmosphere.
When the sun warms, the atmospheric surface water evaporates and form rain droplets that distribute the water all over the world. Due to the energy and heat of the sun, the weather patterns will be changed.
In this article, you have learned what is climate change, greenhouse effect, global warming, and the major factors that are affecting on climate changes. You have also learned about factors that lead to global warming and steps to prevent it. I hope this article helps you to understand the basic concept of climate change.
